<p>Regions of DNA prone to duplication may have played a vital role in human evolution.</p><p>About eight to twelve million years ago, the evolutionary ancestor to humans, chimpanzees, and orangutans appears to have undergone a burst of evolution, driven by duplicated sequences of DNA. This mechanism of genetic change, which has only recently come under scientific scrutiny, may have endowed primates with an evolutionary flexibility that drove the development of different great ape species, including humans. </p>Thu, 12 Feb 2009 05:00:00 +0000digitalservices412023 at http://www.technologyreview.comGenealogy Gets More Precisehttp://www.technologyreview.com/news/410579/genealogy-gets-more-precise/
<p>Rapidly growing databases enable a more complete picture of one’s ancestry.</p><p>Tracing your ancestry via DNA is becoming a popular pastime, thanks to a growing number of consumer tests available over the Internet. At least two-dozen companies sell tests ranging in price from $100 to $900, and public interest is thriving. Most of these tests, however, paint a very rough picture of an individual’s ancestral origins: they’re limited to the direct maternal or paternal line. But that is beginning to change. </p>Mon, 11 Aug 2008 04:00:00 +0000digitalservices410579 at http://www.technologyreview.com
